Working Characteristics
Material Specification :
Cylinder tube Seamless hard drawn low carbon steel tube, honed and hard chrome plated internally to 60 RC increases seal life. Bores : 40 to 300 mm.
Seamless hard drawn brass tube internally polished : Bores : 19 to 65 mm
Piston rod EN8 ground, micro finished and hard chrome plated for lasting seal life and
corrosion resistance.
Seals Piston and cushion seals made from a wear resistant nitrile rubber compound.
The double lip seal design automatically self compensates against wear.
Piston Cast iron.
End cover Cast iron oxidised to prevent corrosion.
Media Air, Oil and inert gas.
Temperature range -20 to 85 degrees cen.
Pressure 150 p.s.i. / 10 bar.
Cushioning available in bore sizes 32 and above only.
Note : The internal finish of the brass tube has been known to improve in continuous operation with the passage of time thereby reducing friction.
